Definitions

  • Such a method and such a device are known in principle and are used, for example, in electrical systems in order to protect people and/or the system itself from the destructive effects of an arc caused by a short circuit or at least to mitigate its effects.
  • animals or falling tools and (damp) dirt can reduce the insulation or the spark gap between two conductors at different voltage potentials in such a way that such an arc occurs.
  • the sometimes very high resulting currents can lead to violent explosions due to the air heating up in a short time.
  • the EP 1 538 722 A2 an arc detection in which the light received from a measuring point is mixed with a modulated reference light source and then divided and passed through two bandpass filters. If a first electrical signal representing light at a first wavelength exceeds a second electrical signal representing light at a second wavelength excluding the modulated reference light, then an alarm is issued.
  • the CH 676174 A the use of a bandpass filter to confine the light received from a measurement point to a range of wavelengths of an arc.
  • the DE 10 2010 016 036 A1 also discloses a color sensor with a red filter, a green filter and a blue filter for detecting an arc.
  • arcs can also occur in electrical systems during normal operation, for example in the form of switching arcs when a live switching contact is separated.
  • the arc in a switching device itself is not usually directly visible, but glowing gas can escape from the switching device, which at least contains metal vapor from the burning switching contacts or arc conducting or arc quenching plates of the switching device.
  • the gas can also contain other components, for example evaporated plastic from the housing of the switching device.
  • the first wavelength ⁇ 1 is in a range between 300 nm and 400 nm and the second wavelength ⁇ 2 is in a range between 650 nm and 750 nm chosen.
  • These wavelengths or wavelength ranges have turned out to be particularly suitable for distinguishing an arc from a glowing gas.
  • the device for distinguishing an arc from a glowing gas has an output which is designed to output a first alarm or a first switching signal in the event of an arc being detected in the monitored area. Accordingly, it is favorable if a first alarm or a first switching signal is output when an arc is detected in the monitored area. As a result, a higher-level controller or monitoring staff can be informed about the fault in the electrical system.
  • the first switching signal can be routed directly to a switching device that automatically disconnects the electrical system from a supplying power grid in the event of a fault. It would also be conceivable for the first switching signal to be routed to a switching device that short-circuits the arc and thus extinguishes it. The resulting high short-circuit current leads to the shutdown of an overcurrent protection switch in the supply line in question. The first switching signal can thus cause both the closing of a switching contact and the opening of a switching contact.
  • the device for distinguishing an arc from a luminous gas has an output which is designed to emit a second alarm/switching signal if a luminous gas containing at least metal vapor is detected in the monitored area and/or a third alarm/switching signal in the In the event that the light detected in the monitored area cannot be assigned to either an arc or a glowing gas that at least contains metal vapour. Accordingly, it is favorable if a second alarm or a second switching signal is output if a luminous gas containing at least metal vapor is detected in the monitored area and/or a third alarm or a third switching signal if the light detected in the monitored area is neither an arc nor a luminous one Gas containing at least metal vapor can be assigned.
  • the third alarm/the third switching signal is output when the ratio I ⁇ 1 /I ⁇ 2 lies between the first and the second threshold value. If value ranges are provided for assigning the detected light to an arc or a luminous gas containing at least metal vapor, the third alarm/third switching signal is output if the ratio I ⁇ 1 / I ⁇ 2 is outside the value ranges provided for the arc or the luminous gas lies.
  • the proposed measures allow the monitoring personnel or a higher-level controller to be provided with additional information that does not necessarily indicate a dangerous situation in the control cabinet. Specifically, not only an arc in the control cabinet is signaled, but also a glowing gas escaping from a switching device and another light source, such as daylight entering the control cabinet when it is opened, or a photo flash.
  • the second and/or third switching signal can in turn be routed to a switching device and separate or close a circuit.
  • the device for distinguishing an arc from a glowing gas has two light-sensitive elements and optical filters placed in front of the light-sensitive elements, the filter or filters placed in front of the first light-sensitive element predominantly light of the first wavelength and the filter or filters placed in front of the second light-sensitive element predominantly Allow light of the second wavelength to pass.
  • the first and/or the second optical filter can be designed as a bandpass filter. In this way, two identically constructed light-sensitive elements can be used to detect the light from the surveillance area. In principle, however, the use of a high-pass filter and a low-pass filter is conceivable.
  • the first optical filter allows light in a wavelength range between 300 nm and 400 nm and/or the second optical filter allows light in a wavelength range between 650 nm and 750 nm to pass, or if a maximum permeability of the first optical filter is in this wavelength range and in particular at 350 nm and a maximum transmission of the second optical filter is in the above wavelength range and in particular at 700 nm.
  • these wavelengths or wavelength ranges have turned out to be particularly suitable for distinguishing an arc from a glowing gas.
  • FIG. 1 shows a diagram of the absolute irradiance I as a function of the wavelength ⁇ for an arc (graph A) and a luminous gas containing at least metal vapor (graph B).
  • the first wavelength ⁇ 1 is selected in a range between 300 nm and 400 nm 2. and the second wavelength ⁇ 2 is selected in a range between 650 nm and 750 nm. in the in 1
  • the ratio I ⁇ 1 / I ⁇ 2 is 5 in the case of the arc (graph A) and 0.0125 in the case of the luminous gas (graph B). If the value 2.5 is selected for the first and second threshold value, then the measured ratio I ⁇ 1 /I ⁇ 2 is clearly assigned to an arc or to a luminous gas at least containing metal vapor.
  • the two light-sensitive elements 2a, 2b are preceded by two optical filters 6a, 6b, with the filter 6a placed in front of the first light-sensitive element 2a predominantly light of the first wavelength ⁇ 1 and the filter 6b placed in front of the second light-sensitive element 2b predominantly light of the second wavelength ⁇ 2 can happen.
  • the two optical filters 6a, 6b are advantageously designed as bandpass filters.
  • the device 1 is connected to an optional light guide 7, which guides the light from the monitored area 3 to the optical filters 6a, 6b or to the light-sensitive elements 2a, 2b.
  • the device 1 also has an optional alarm output or switching output 8 .
  • the evaluation unit 5 determines the ratio I ⁇ 1 / I ⁇ 2 between the first intensity I ⁇ 1 and the second intensity I ⁇ 2 and assigns the detected light to an arc if said ratio I ⁇ 1 / I ⁇ 2 is greater than a predeterminable first threshold value and to a luminous gas containing at least metal vapor if said ratio I ⁇ 1 /I ⁇ 2 is smaller than a predeterminable second threshold value.
  • the value 2.5 is selected in particular for the first threshold value and the second threshold value. Of course, all the others in connection with the are also conceivable 1 mentioned threshold values.
  • a first alarm or a first switching signal is preferably output via the alarm output or switching output 8 if an arc is detected in the monitoring area 3 .
  • the detection of an arc or a glowing gas can also be passed on in other ways.
  • the measuring device 4 can be designed as an analog-digital converter, which converts the electrical signal of the light-sensitive elements 2a, 2b into a digital value, and the evaluation unit 5 as a microprocessor, in which a software algorithm for determining the ratio I ⁇ 1 / I ⁇ 2 and is carried out to assign the received light to an arc or to a glowing gas.
  • a light-sensitive element 2a, 2b and a measuring device 4 can form a structural unit.
  • this component can output an (amplified) analog signal or a digital value directly.
  • a light-sensitive element 2a, 2b and an optical filter 6a, 6b can form a structural unit.
  • the housing of the light-sensitive element 2a, 2b can be colored accordingly.
  • a combination of a light-sensitive element 2a, 2b, a measuring device 4 and an optical filter 6a, 6b in one structural unit is also conceivable.
  • the device 1 according to the invention can reliably distinguish an arc that is visibly burning in the switch cabinet 9 from the glowing gas and does not emit a false alarm signal or switching signal in such a situation. This is only issued if an arc is visibly burning in the control cabinet 9, for example because animals crawling into the control cabinet or falling tools reduce the insulation or spark gap between two conductors at different voltage potentials so much that such an arc occurs.
  • the first switching signal 8 can be routed to the inputs of the switching devices 14a . . . 14c, for example. If an error occurs, the switching devices 14a..14c are closed and thus extinguish the arc burning between the phases. The one by the conclusion of the course Caused overcurrent triggers the overcurrent circuit breaker 10a..10c or the overcurrent circuit breaker 11 in a row, whereby the system is ultimately disconnected from the power grid.
  • the first switching signal 8 can also be routed out of the control cabinet 9 and, for example, cause an alarm. It is also conceivable that the switching devices 14a..14c are connected to ground, as a result of which the phases can be short-circuited to ground (and to each other) using the switching devices 14a..14c.
